A SPH^EIACEOUS TAKASITE ON PEZIZIA. 77 



are not attenuated at the two extremities, hence this parasite seems 

 to me to be a new species. 



Note by the Editor. — This appears to be an interesting 

 parasite which M. de ISeynes has found on Peziza and Xylaria. 

 It is always unsafe to hazard an opinion upon a fungus without 

 peeing it ; but from the description and figure we do not think it 

 probable that it is a species of Lophwstonia. There is really no 

 evidence at all that the parasite is Ascomycetous. In neither in- 

 stance did M. de Seynes detect asci. From the drawing the 

 perithecium has the appearance of being membranaceous, and not 

 carbonaceous. The measurement of the fruit is not given, and 

 there is no appearance of the sporidia breaking up into joints as 

 in Perisporium. We think that in the absence of any trace of asci 

 it is assuming too much to declare the parasite to be Ascomycetous. 

 It is to be hoped that M. de Seynes will meet with it again, and 

 complete his observations. 



FUNGI BRITANNICI EXSICCATI. 



The seventh and last century of the first series of this c«jllcction 

 has recently been issued, and will be of much interest to Mycolo- 

 gists, inasmuch as it contains 20 species that are new to the British 

 Flora, i.e., Phyllosticta Verouicre, Desm. ; Plioma Lonicera?, C. ; 

 Phoma subordinaria, Desm. ; Phoma vitis, Bon. ; Phoma erra- 

 bunda, Desm. ; Macrosporium cladosporioides, Desm. ; Diplodia 

 syringse, Awd. ; Eamularia armoracite, Fckl. ; Periconia brassi- 

 cjecola, B. & Br. ; Ramularia stellari^e, Fckl. ; Peziza cerastiorum, 

 Wallr. ; Diaporthe scobina, Nke. ; Diaporthe Euphorbias, C. ; Spo- 

 ridesmium cladosporii, Ca. ; Melanconis modonia, Tul. ; Diaporthe 

 Laschii, Nke. ; Cucurbitaria euonymi, C. ; Fusidium Geranii, 

 Fckl. ; iSphserella ditricha, Ir. ; Pleospora culmorum, C. Of these 

 five are new to science, of which descriptions will shortly be pub- 

 lished. 



Constant applications were being made from abroad for complete 

 sets of these s})eciniens from the commencement, which it was im- 

 possible to supply, and in order to meet these recpiirenients in the 

 only way possible, it was resolvtd to bring the fiist series to a 

 close, and commence a new series during the coming year. 

 The second series will, it is believed, present improvements on the 

 first. It will be issued in quarto, similarly to Fuckel's " Fungi 

 Rhenani," and to a limited extent figures of the iruit will be given 

 side by side with ndcroscopical species. Each fasciculus, contain- 

 ing a hundred specimens, will be published at one guinea, and al- 

 though many of the species included in the first series will be 

 repeated, these will be supplemented by other species not yet pub- 

 lished. It is scarcely probable that more than one century will be 

 published during a year. Subscribers names may be sent to the 

 Editor.
